Changes:
- Added support for multiple SFD files.
- New option `-L' to provide a ligature mapping file.
- New option `-w' to emit PostScript encoding vectors for
subfont files to be used with pdfLaTeX.
- Add support for a configuration file (ttf2pk.cfg) which can
read more than a single map file, similar to pdfTeX.
- Support for character codes greater than 0xFFFF.
- ttf2tfm no longer assumes that the x-height is always 400 PS
units.
ttf2pk/ttf2tfm permit using TrueType fonts with teTeX.
To be used for pkgsrc-wip/cjk-latex & friends (fixes and
a working cjk-latex-wadalab font pkg to be committed too)
